Abstract
A paper web is moved from an upstream source by a transport mechanism, and is cut into individual sheets of paper by a blade. The transport mechanism operates in a start-and-stop motion cycle to move the web intermittently. During the stop periods, the blade cuts the web. The transport mechanism includes a driving member, and also includes a driven member for performing a start-and-stop motion in response to simultaneous non-stop motion of the driving member. The driven member is arranged to cause the web to move to the blade, and each cutting occurs when the driven member is in a substantially stopped position. The interface between the driving member and the driven member is mechanical only.
Claims16
A system for moving a paper web from an upstream source, and for cutting the paper web into sheets, the system comprising:
- a blade for cutting the web into the sheets;
- and
- a transport mechanism for operating in a start-and-stop motion cycle to move the web so as to allow the blade to cut the web during stops;
- wherein the transport mechanism includes a driving member, and also includes a driven member for performing a start-and-stop motion in response to non-stop motion of the driving member, the driven member being arranged to cause the web to move to the blade;
- and
- wherein each of the stops occurs when the driven member is in a substantially stopped position.
A web cutting device for moving a paper web from an upstream source, and for cutting the paper web into sheets, the system comprising:
- a driving member;
- a driven member intermittently driven by the driving member, the driven member being arranged so as to move the paper web;
- and
- a blade activated when the paper web and the driven member are substantially stopped, and while the driving member continues in motion.
A method for moving a paper web from an upstream source, and for cutting the paper web into sheets, the method comprising:
- operating a driving member in substantially uniform motion;
- interfacing the driving member with a driven member that automatically is driven to move in a stop-and-start manner;
- moving the paper web in response to the driven member;
- and
- cutting the paper web when the driven member and the paper web are stopped.
